Digital Design Flashcard 1

Analyze this circuit: (i)Input A goes to one input of an AND gate. (ii)Input B goes to both a NOT gate and to the second input of the AND gate. (iii)The output of the NOT gate is the second input to an OR gate. (iv)The output of the AND gate is the first input to the OR gate. Write the Boolean equation and simplify it.

Convert (4F9)₁₆ to octal.

Represent -45 in 8-bit 2’s complement and add 1 to the 2's complement

What is the dual of the Boolean expression: A + AB'?

Which combination of gates can perform the function of an OR gate? Options: NAND + NOT, NOR + NOT, AND + NOT, XOR + AND

What is the Binary code equivalent of Gray code 11100?

Divide (111100)₂ ÷ (11)₂ using binary division. (Convert to decimal and calculate)

What is the 9’s and 10’s complement of the decimal number 5472?

A logic circuit outputs HIGH only when the number of HIGH inputs between A and B is odd. Which logic gate expression does it indicate?
